Multiple SFR As A Multi family/Unit?

[Kyle Myers]

I'm aware of the pitfalls of SFR vs Multi in regards to being susceptible to vacancies and I'm sure I will kick myself when I hear the answer, but if a person buys a batch of SFR, say over 8 at once, is there a reason they can't be treated/managed as a multi unit portfolio? What's the difference in having 8 unit apartment and 8 unit/Single homes in a small neighbor hood or geographical area?

Thanks for any input
